It's about this:-
Not just an interesting read, (which is why I'm reading it), but, a call for action! (your post your call).
Don't use BP or Esso or any of the supermarkets, plenty of heating oil tanks up and down 
I'm prepared to take action after all, filling my tank now costs over £100, but lets make sure we aren't wasting more time and money, go on, show off your googling prowess and proudly display the facts.
£100 + to fill your tank............wow, must be a big motor. google by the way does not show where the supermarkets fuel comes from, only the fact that it is all low grade stuff,judging by the number of complaints
....... think we need to spend £100 + to tank your vehicle up and then follow an Asda or Tesco tanker to see where they go to fill up
